1. Explanation:

• Step 1: Recall the formula for the area of a triangle

The formula for the area of a triangle is \(A=\frac{1}{2}\times base\times height\). In this triangle, the base is \(13.1\) cm and the height is \(6.9\) cm.

• Step 2: Substitute the values into the formula

We substitute \(base = 13.1\) cm and \(height=6.9\) cm into the formula \(A=\frac{1}{2}\times base\times height\). So \(A=\frac{1}{2}\times13.1\times6.9\).
First, calculate \(13.1\times6.9 = 90.39\). Then, \(\frac{1}{2}\times90.39 = 45.195\) \(cm^{2}\).

1. Answer:

\(45.195\) \(cm^{2}\)
